I saw someone on TikTok say, “what if this is the 12 hours Violet doesn’t remember?” and I genuinely haven’t known peace since 😭💀

xaddy where you at

[èvieane]

ㅤ ‍‍‍‍‍‍ ‍‍‍‍‍‍ ‍‍‍‍‍‍ Oh, they are going to have to use chains on me and keep me sedated if i get even the slightest angst scene with Xaden here. I AM GOING TO DEVOUR IT SO BAD!! Just give it to me 😩

[Ss]

IM SAT.
Xaddy I need you.

[Grace Btrs (semi ia - mostly overwhelmed)]

WHATEVER THIS IS, I AM EATING IT UP. Crumbs, dust, and all.

Okay also so
Since this is not listed in the Empyrean Series thread, but it's added on RY profile alone (like a stabdalone would be)
Which leads me to believe it is not a novella about the main characters
It's probably some world lore like the Fables or the codex or an extended glossary or the guide to dragons or ALL OF THEM COMBINED

[Rachel Louise ☆]

WHAT DO YOU MEAN THERE'S A FOURTH WING NOVELLA BEING RELEASED ON MY BIRTHDAY I'M GONNA THROW UP

[Bloomy Soul]

Damn.
🔥 🔥 🔥
XADDY 🫦🫦🫦

[Giulia ❀]

It’s gonna be the codex I just know it.
Also, I think soon Rebecca will finally release on her website the bonus chapter she was working on last summer about Xaden’s pov while Violet was being tortured in Iron Flame.
I CAN’T WAIT FOR SEPTEMBER TO BE HERE PLS REBECCA HURRY WITH THAT BOOK 4 BC I’M CRAVING IT

[giu ౨ৎ]

i’m so ready for this one!! i can’t wait for it to be released

[Tami]

We only know one thing so far: this is not the graphic novel, based on Rebecca Yarros’s Instagram post.

She shared a long message thanking readers after the book unexpectedly went to #1 on Amazon before it even had a title or cover. She also confirmed two important things:

● This does not change the timeline for book 4.
● This is not the upcoming graphic novel.

So yes, surprise project confirmed… just not that one.

✎Pre-Read

20/4/2026 predictions
My top theories for what this could be (in a slight order of how likely I think they are) are:
➛ Book Of Brennan (I just really want this)
➛ The Fable Of The Barons (could tell us something about defeating the Venin)
➛ A story of the Six (same with the last one)
➛ Lyra's (one of the Six) journal (same with the last 2)
➛ Field guide to dragon kind/some other text book (interesting knowledge and possible tell us about the dragon who is lying?)
➛ Violet's dad's journals (something about the isles for help defeat Venin?)
➛ The Codex (I think it would be a bit boring so I kind of doubt it)
➛ novella about Violet before she joined the quadrant (fits with the theory about her second boyfriend)
➛ novella about what happened to Bohdi in the battle (revealing him as the brother?)
➛ novella about what happened to Brennan in the war (confirmation about Naolin turning Venin and maybe even their relationship)
➛ a novella about what happened to everyone else in the 12 hours (unlikely in my opinion because I feel like we would just get it at the start of book 4)

[jo (taylor’s version)]

[Momo]

4/26

Already on order.

Now to play the guessing game.

I've seen a couple of theories online. But I think this will be the Codex, what about you?

[Amelia]
